LOAD-ELEVATOR.

Application filed June 21,

Be it known that I, AXEL YUGSTROM, a citizen of the United States,residing at Lindsborg, in the county of McPherson, State of Kansas, haveinvented certain new and useful Improvements in Load-Elevators; ar fldnl clear, and exact description of the invention: such as will enableothers skilled in the art to which it appertains to make and use thesame.

the provision of This invention relates to load-elevators.

- One object of the invention is to provide means for unloading Wagonsby lifting the body of the latter from its running-gear and dumping theload therefrom into a suitable bin or receptacle.

Another object of the invention resides in a comparatively simple,inexpensive, durable, positively elevating vehicle-bodies for thedumping therefrom of grain or other mate rial into a receptacle. 1

With these and other objects in View the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacr ficing-anyof the advantages of the invention.

In the drawings, Figure 1 is a perspective view of the invention. Fig. 2is a top plan view. Fig.3 is a detail view of one of the legs,illustrating the connection of the hanger therewith for the mounting ofone of the double pulleys. Fig. 4 is a detail view of one of the brakes.

Referring now more particularly to the ac companying drawings, theinvention comprises a frame consisting of legs 1, 2, 3, and 4, upperside beams 5 and 6, and upper end beams 7 and 8, there being braces 9and 10, connecting the side pieces 5 and 6 with the corresponding legs.Braces 11 and 12 are connected to each end piece 7 and 8 and with thecorresponding legs, there being additional braces 13 and 14, extendingacross the ends of the frame and connecting the corre sponding legsimmediately beneath the corresponding cross-pieces 7 and 8.

Journaled in suitable bearings 1 5, arranged upon the upper faces of theside pieces 5 and Specification of Letters Patent.

I 6, are shafts 16 and 17, the shafts being arranged at opposite ends ofthe frame. Mounted upon the shaft 18 and 19, while the shaft 17 haspulleywheels 20 and 21 secured thereupon, all of the pulley-wheels beingprovided with side flanges to form grooves to guide the hoistingcables22, connected therewith in any suitable manner, each cable-there beingfour of them-having a hook 23 connected at its lower or free end.Arranged adjacent the pulley-wheels 19 and 21 are ratchet-wheels 24 and25, respectively, the said ratchet wheels being also confined within theend and side pieces at the top of the frame. Pivoted in suitablebrackets 26 and 27 by means of suitable pivot-pins 28 are levers 29 and30, which are designed to engage the teeth of the corres ondingratchet-wheels 24 and 25, there being suitable helical or other springs29 and 30 designedto engage the inner ends of the respective levers, asshown, to hold the inner ends of the said levers normally in engagementwith the corresponding ratchetwheels. The outer end of each lever 29 andeach to the braces 13 and 14.

16 are pulley-wheels 30 has connected thereto a suitable flexible 1 pullupon the Secured to the inner faces of the legs 1 and -2 of the frameare hangers 34, between each of which and the respective legs is a shaft35,

upon each of which shafts is mounted a double pulley 36. Mounted in theinner side I 37 of each double pulley 36 and secured to the periphery inany suitable manner is a rope 38, whose upper end is connected to therespective pulleys 39 and 40 of the respective shafts 16 and 17.Connected to the outer side of each double pulley is another cord 41,the said cord having each of its ends connected to the outer sides ofsaid pulley-wheels with its bight portion having connection with a hook42, designed to be engaged with a whiffletree (not shown) whereby thesaid double pulley 36 may be rotated upon the pulley of the said rope41, the rope being guided from the left-hand double pulley 36 by meansof an eye 43, arranged at the end at a right angle to the body 44 of abracket 45, which is secured in any suitable manner to the outer sideface of the leg 1, the rope leading from the other double pulley 36being ITO guided through the guide 33, secured also to the leg 1. Itwill be observed that the lower ends of the legs 1 and 2 are increasedin thickness, as at 46, and that each one of these legs 1 and 2 has aprojection 47 directed toward the corresponding legs 3 and 4, therebeing a brake-band 48 secured to each projection 47 the lever 49,pivoted, as at 50, to the bracket 51, which latter is secured in anysuitable manner to the respective legs 1 and 2.

When it is desired to unload a vehicle of grain or other material anddischarge it into another receptacle, (not shown,) it is simplynecessary to engage the hooks of the hoisting ropes with the body of thevehicle. The horse or horsesshould then be released from the vehicle andused for hoisting purposes. In other words, after detaching the animalsfrom the vehicle, it is simply necessary to engage the hook 42 of therope 41 with the swmgletree or whiflletree (not shown) and start thehorses forwardly. The forward movement of the animals will rotate thedouble-pulley wheels 36 and through the rope connections 38, which areconnected to the pulley-wheels 39 and 40, will cause the shafts 16 and17 to rotate, and consequently lift the body of the vehicle from therunning gear by reason of the pulleys connected to the shaft at the topof the frame, the said body being elevated until it reaches the chute52, which latter is secured upon the brace 14 and down which it mayslide to a bin or receptacle. (Not shown.)

In order to prevent the body being carried too far upwardly, the brakesat the ends of the frame may be employed for locking the double-pulleywheels against movement. Of course in order to incline the body of thevehicle when it has reached the predetermined height within the framethe brakelever secured to the leg 2 may be operated to prevent furtherupward movement of the hoisting-ropes at the rear of the frame, whilethe opposite hoisting-ropes may be permitted to move upwardly a littlefarther to incline the body of the vehicle and insure the discharge ofall the grain or material and having connection with' from the latter.It is obvious that a pull upon the ropes connected with the lovers 29and 30 will disengage the inner ends of the levers from theratchet-wheels 24 and 25 and permit of a ready lowering of the body ofthe vehicle upon its running-gear.

What is claimed is V 1. A hoisting device comprising a frame,oppositely-disposed rotatable shafts mounted in the top of the frame,pulley-wheels connected with the said shafts, a ratchet-wheel connectedto each shaft, hoisting-cables connected to some of the said pulleys,doublepulley wheels mounted near the bottom of the frame, a connectionbetween each doublepulley and one of the pulleys of each shaft, a ropeconnected with each of said double pulleys, means for braking thedouble-pulleys, levers adapted to prevent backward movement of theaforesaid ratchet-wheels, and means whereby said levers may bedisengaged from the ratchet-wheels.

2. A hoisting device comprising a frame, oppositely-disposed shaftsrotatably mounted in the top of said frame, each shaft having pulleysand a ratchet-Wheel secured thereto and mounted within the frame, eachshaft also having a pulley mounted exteriorly of the frame,hoisting-cables connected to the pulleys arranged within the frame,doublepulley Wheels mounted in the bottom of the frame, a ropeconnection between the said double pulleys and the pulleys mounted uponthe said shafts exteriorly of the frame, a rope connected to said doublepulleys to rotate the same, brakes secured to the frame for braking thedouble-pulley wheels against rotation, a lever adapted to preventbackward rotation of the ratchet-Wheels, means whereby the levers may bemoved out of engagenlent with the ratchet-wheels, and a chute connectedto one end of the frame near the top 1 thereof.

In testimony whereof I iLfllX my signature in presence of two witnesses.
